Word Problem 12
Problem 12: In examination 40% of students fail in Math 30% fail in English and 10% fail in both. Find pass percentage.
a. 40% b. 50% c. 60% d. 70%
— percentage calculation —
pre employment exam questions, basic math test with answers, mathematical test, numerical logic test
Failure in Math= 40%
Failure in English= 30%
Failure in Both= 10%
Pass %age =?
So, 40% students were passed
Alternatively we can use Van Diagram to solve this problem;
Failure in English only= 30-10=20%
Failure in Math only = 40-10=30%
Fail in both = 10%
Total failure = 20+10+30=60%
